We propose a method to acquire interactions to axial objects with a sensor sheet equipped with many magnets and several magnetic sensors that can be wrapped around various axial objects. It can cover an axial object, and when a force is applied to the sensor sheet, it deforms, and the embedded magnets are moved. Thus, the magnetic flux density on the sensor sheet is changed according to the applied force, the magnetic sensors can detect the transformation, and finally the system calculates the applied force. In this paper, we confirmed that proposed system can classify the interactions and estimate the intensity.
